A54SX32A-1FGG484M

Overview

The A54SX32A-1FGG484M is a military-grade Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V, supporting up to 249 user I/Os in a 484-pin Fine Pitch Ball Grid Array package. The device achieves a maximum system performance frequency of 250 MHz with an internal clock capability of 350 MHz. It supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal programmable interconnect elements
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1

Applications

• Military avionics and defense communication systems requiring high reliability
• Spacecraft onboard data handling and signal processing
• Harsh environment industrial control applications demanding extended temperature ranges

Procurement Notes

Verify that the ordering suffix 'M' corresponds to the specified military temperature grade (-55°C to +125°C) as defined in the official datasheet. Confirm compliance with export regulations such as ITAR or EAR, as these devices may be subject to international traffic controls. Ensure the specific speed grade '-1' matches the required timing constraints for the target design implementation.

Selection Notes

Select this component when a nonvolatile FPGA solution with deterministic timing is required for extreme environmental conditions. The 484-pin FBGA package accommodates designs needing over 200 user I/Os. Verify that the 2.5 V core voltage aligns with the system's power distribution network and that the 5 V tolerant I/Os are sufficient for interfacing with legacy peripherals.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a single-chip solution that integrates complex logic functions previously requiring multiple CPLDs. The military variant ensures operation across the full -55°C to +125°C range.
